   @C6When a message is deleted, the actual message body remains in the files.  This can fill the disk space rapidly.  The @HCOMPRESS@R@C6 command rebuilds the message bases and removes all wasted space from the files, thereby freeing up extra disk space and making the system file access time faster.  The status of each individual message remains unchanged.@R
